SPECIFICATION forming part of Letters Pate t No. 547,656, dated October8, 1895.

Application filed Me. 14, 1295.

To aZZ whom, it may concern;

Be it known that I, ALFRED L. BARON, of Tiffin, county of Seneca, Stateof Ohio, have invented certain new and useful Improvements inCan-Guards, of which the following is a specification, reference beinghad to the accompanying drawings.

The object of my invention is to produce improvements in cans or vesselsfor containing liquids, by which the cost of manufacture of the guardedcan is diminished and its durability and compactness are increased, andalso in coverings for cans by which the fragile material, usually ofglass, of which the cans are made, is effectually protected againstdamage or injury from outside blows orshocks.

In the accompanying drawings, Figure I is a side elevation of my can.Fig. II is a cen- Fig. III is a bottom plan view thereof; and Fig. IV isa view of the lateral jacket detached, showing the means of forming thebase or bottom part thereof.

Referring to the figures on the drawings, 1 indicates a can-body, whichmay be made of suitable shape, size, and material, usually glass.

2 indicates the head, preferably made of tin or other sheet metal andprovided with a spout 3 and a screw-cap 4.. It is provided with a flange5 surrounding a collar 6 of the canbody, to which it may be secured bysuitable means-as, for example, plaster-of-paris. The periphery of thehead is preferably screwthreaded, as indicated at 7, to receive and holdthe flanged internally screw-threaded annulus 8, of which 9 indicatesthe flange.

10 indicates the jacket, which is preferably made of interwovenspring-wire, preferably consisting of aseries of interwoven springwirespirals 11.

In practice a cylindrical jacket of the material is manufactured to fitthe size of the can to be protected, as illustrated in Fig. IV. It maybemade by the well-known machine for weavingbed-mattresses, whereinterwoven spirals are employed; but any suitable method of manufacturemay be substituted therefor. When the cylinder is completed, the bottompart maybe formed by placing it over an Serial No. 541,771. (No model.)

7 iron cylinder 12. (Illustrated by dotted lines in Fig. IV of thedrawings.) This cylinder corresponds in shape and size to the can forwhich the cylinder or jacket is designed to be fitted. A die (indicatedby dotted lines and designated at 13 in Fig. IV of the drawings) isforced against the end of the iron cylinder, so as to compress'the endof the jacket and to mash the spirals thereof, thereby causing them tolie nearly at right angles to the side walls of the jacket after it islifted from the iron-cylinder, as indicated by 14 in the drawings. It isthen placed over the glass can or vessel, the inturned edges 15 formingthe bottom protection for the same. Afterward the upper part of thejacket is gathered by suitable meansas, for example, a temporaryconfining-annulus, (notillustrated)-until the edges approach theperiphery of the head 2. The annulus 8 is then screwed in place, itsflange 9 serving to permanently confine the upper end of the jacket inplace. When this has been accomplished, the an nulus8 may be secured inposition, as by soldering, the tem porary annulus being no longernecessary, and the can properis completed. Inasmuch, however, as the rawedges 15 of the can-jacket are exposed and unless great care beexercised in the manufacture of the jacket they may tend to catch uponan obstruction with which they may come in contact, I prefer to employthebottom peripheral bends or spirals 17 as spring cushions or yieldingsupport for a plate-metal bottom 18. The bottom 19 of the glassreceptacle is preferably concave, and the plate-metal bottom is alsosimilarly formed so as to give a smooth, level bearing or supportingsurface 20 around its lower periphery, its edge being turned up toconstitute an annular groove for the reception of the convolutions ofthe jacket and thereby bringing the upper edge of the bottom platesubstantially in line with the bottom of the can-body to form aneatfinish and to, prevent the lower convolutions of the jacket fromcoming in contact with the adjacent surfaces when the can is slightlytilted upon its edge. The platemetal bottom may be secured to thespringcushions in 'a variety of ways; but I prefer to employ for thispurpose a wire frame21, bent to span and conform to the contour of thebottom of the can-body, as indicated at 22, and thence passing upwardlythrough diametrically-opposite spirals 23 in the jacket, termi- 5 matingin eyelets 24: near the upper end of the jacket. An indented diametricalgroove 25 in the bottom of the bottom plate serves by engagement withthe frame not only to hold the bottom plate in position, but also embeds[0 the material of the frame 21, so as to protect it against strikingany obstruction with which it ordinarily may come in contact.arrangement a convenient means of rigidly fastening the frame 21 inplace may be conveniently provided. As additional means of seeming theframe 21, I prefer to employ radial loops 27, secured, as by solderingor otherwise, under the flange 0, through which the eyelets may bepassed, the eyelets being free to slip through the loops when the partsare assembled. The engagementof the eyelets with the bends of the loopstends to hold the frame 21 in place, but an effective and reliable unionof the frame with the loops may 25 be insured by inserting the eyelets2S ofthe bail-piece 29 through the eyelets 24 at right angles to them,the eyelets 28 being in practice of sufficient size to lock the eyelets24 in position within the loops.

A simple and convenient form of tilting handle consists of a wire frame29, having its ends 30 bent at right angles to the frame and insertedthrough the meshes of the jacket before it is placed upon the can. Afteritis 5 in position upon the can it is firmly held in place by thepressure of the interiorwall of the jacket against the exterior wall ofthe can-body.

\Vhat I claim is- 1. The combination with a can body, abettom plate andintermediate yielding spring cushions, of a frame passing underneath thebottom plate, and mechanism upon the under side of the bottom plateco-operating with the 5 frame to hold the same in place, substantiallyas specified.

2. The combination with a can body, abottom plate and intermediateyielding spring cushions, of a frame passing underneath the bottomplate, and a groove in said bottom plate for the reception of saidframe, substantially as specified.
